This pulling may deform the O-ring and cause leakage.
In view of the above-mentioned shortcomings, a renovated coffee maker sealing structure has derived.
It is the primary object of the present invention to provide a gasket for sealing a heating chamber of an electronic coffee maker, which the gasket seals the heating chamber in a secure without leakage consideration.
It is another object of the present invention to provide the gasket for sealing a heating chamber of an electronic coffee maker, which the gasket has a longer life span.
